CASEMENT AND noon LOCK.

Be. it. known that 1, JAMES C. Gnirr n, a citizen of the United States, residing at- Erie, in the county. of Erie and State-0f Pennsylvania, have invented new and useful Improvements in Casement and .;Door Locks, of whichthe following is a specification;

This invention relates to casement.-

casing iorms a more desirable base forthe door locks and consists in certain improve ments in the constrnction'thereof as will be hereinafter fullydescribe'd and pointed out in the claims.

The lock is. ;.particular'iy designed for doors such-as garage doors where it' is desired to lock theIdoor'in difi'erent position and-particularly an open position;

v I accompanying' drawings as follows Figure 1 shows a plan ,view of;a door a a part of a casing, .the cas ing. being partly broken away .to {.better show construction.

tl1e line-3 '3in Fig.1. Fig. i an endview 1 marks thedoor casing, 2 the door and 3 A loc lring'rod 4 is pivotallymounted on a" hinge plate 5. The hinge plate 5 consists cnred tothe door casing by means of screws,

return bend 91 The end of the locking rod" at is placed between the return bend 9 'and the lip 8 and secured by the pin 10 which forms the pivotal joint for, the hinge between the lod 4 and the hinge plate 5.

A locking plate 11, preferably in he form of a loop with the extending feet 12 is secured to the door by means of screws 13' 'bination of a hinge plate; a lockmg'rod .pivotally mounted on the plate and'h'aving extending through the feet or flanges 12. The sides of the loop are provided with the slots 14 through which the rod 4: extends. The rod '4 is provided with the notches 15 which are so spacedand of such. size as to engage the sides of the locking plate-11 at the bottoms of the slots 14. The rod '14 is preferably" provided also with othernotches as 16 so as to lock the door in will lock the door in a closed position and the notches 15 will lock the door in an open position. It will be observed that when the door is Specification ofii'retters Patent. application filed une 24,-1914. SerialiNo. 847,003.

opened; the rod dwill swingon the pin 10 and shdethrough the slot 14, the bottom of the rod resting on the bottom of the slot.

-When the notches 15 come into register with the sides of the locking plate they drop intoengagement with the plate,'thus locking the door in the position desired. It is'preferable to place this locking-rod at the upper end of the door so as to be-out' of the way andj-the rod in that the rod may be spaced from the hinge so as to more'readily lockthe door in Y an open position. In order to readily dis engage the rod when thus locked I'provide a trip lever 17. This is arrangedw-ithinthe ,sldes of the loop 11 and pivotally omounted the loop. The outer ,end of this tripllever has a flexible cord orchain 19 depending from it terminating with a handle or ring r on the pin 18 extending between the sides of extends under the rod 4 and the innerend 4 It will be observed that the device may side by simply removinglt e pin an with drawing the rod from the slot 14. The hinge 20 by which it may be readily operated. I l

plate is formed so that it will workequally f well for a door opening either to the right or left and the locking plate is also adapted foropening either side. 1. 9

'What'I claim as new is I 1. Ina casement and door lock, the combination of a hinge plate; a locking rod pivotally mounted on the plate andhaving a-locking notch in the bottom thereof; a

and a trip device carried by the locking ghate and 'adaptedto lift the 'rod to disengage-it fromthe plate.

2. In a casement and doorlock..the coina locking notch the bottom thereof; and a locking plate in theformfof. a loop with side flanges or feet extending therefrom, said loop having slots in the side walls thereof through which ,the locking rod extends, a

1 0 locking plate adapted to pass into the notch in the rod as the,rod slides over the plate;

g .therod relaing notch in the bottom thereof; a looking no plate fihe form of a loop with side flanges or fees; extening refrom, said 100p havin the side Walls thereof through we Eoeking rod extends, e side of the lento to enter the notch in the g ehe rod relatively to the plate; trip lever pivotally mounted Within :he cop wifih one end under the rod and the opposite end being adapted to be operated to trip the rod. 1

in e easement and door lock, the combination of a hinge plate formed with a securing base and a hinge lip with areturn bend; a locking ro having notches in the bottom thereof and pivotally secured between the lip and the return bend on the hi ge piae; a 1 relate in "he form of a loop having slots in the side Walls thereof through which the locking r03x passes, sides 0? the loop being adapted toenter the notches in the rod to lock the rozi in place; and a trip lever pivotelly mounted between the sides of the loop and adapted to trin the looking rod.

In testimony whereof I have hereunto set my hand in the presence of two subscribh1g Witnesses.
